这项研究调查了为高频听力损失的听者提供可听语音信息的好处是否存在限制。在一组10名患有不同程度高频听力损失的听众中，测试了不同呈现级别的语音识别。对于这些听力损失的听者中的每一个，当听力损失超过55dBHL时，识别性能达到渐近线(或=3000赫兹)，往往对识别分数几乎没有改善。相比之下，对于听力损失严重到严重的平坦的听者，向低频区域提供可听语音确实显示出随着语言可听度的提高而改善的情况，尽管该听者的阈值高于55dBHL。这项研究进一步支持了这样一种观点，即试图为高频听力损失严重的地区(或=3000赫兹)提供放大信号可能不一定会使许多听力损失患者受益。
This study investigated whether there are limitations on the benefit of providing audible speech information to listeners with high-frequency hearing loss. In a group of 10 listeners with various degrees of high-frequency hearing loss, speech recognition was tested across a wide range of presentation levels. For each of these listeners with hearing loss, recognition performance reached an asymptote of or = 3000 Hz), where hearing loss exceeds 55 dB HL, tended to produce little or no improvement in recognition scores. In contrast, providing audible speech to lower frequency regions for a listener with a flat, severe-to-profound hearing loss did show improvement with increasing speech audibility, despite this listener's thresholds being greater than 55 dB HL. The present study adds further support to the idea that attempting to provide amplification to regions with severe high-frequency hearing loss (> or = 3000 Hz) may not necessarily benefit many individuals with hearing loss.
